2450H • A major error notification from the RJ71EIP91 has
been detected.
• The I/O module or RJ71EIP91 is not mounted
properly or was removed during operation.
• Take measures to reduce noise.
• Check the connection status of the extension cable.
• Check the detailed information (system
configuration information) by executing module
diagnostics using the engineering tool, and check
the module corresponding to the displayed slot
number.
• Reset the CPU module, and then switch it to RUN
mode. If the error occurs again even after the above
action is taken, the possible cause is a hardware
failure of the module on which the error occurred.
